Background: Malathion (MT), an organophosphorus pesticide, induces hepatotoxicity and is associated with hyperglycemia and the development of diabetes mellitus.  Objectives: This study was aimed to evaluate the effects of sub-acute exposure to sub-lethal dose of MT in the liver of diabetic rats.  Methods: Non-diabetic and streptozotocin-induced diabetic rats received MT at a dose of 150 mg/kg...

Salinity is a major abiotic stress that poses great obstacles to wheat production, especially in arid regions. The application of exogenous substances can enhance plant salt tolerance and increase its productivity under salinity stress. This work aimed assess the mechanisms selenium (Se) at different concentrations (2, 4 8 ?M SeCl2) mitigate hazardous impacts toxicity physiological, biochemical...

Background: Exercise stress was shown to increase oxidative stress in rats. It lacks reports of increased protection afforded by dietary antioxidant supplements against ROS production during exercise stress. We evaluated the effects of vitamin E supplementation on renal non-enzymatic antioxidants in young rats submitted to exhaustive exercise stress. Methods: Wistar rats were divided into three...

background:in recent years, the use of chemicals in agriculture, industry, and public health has become so common that the environment is continuously contaminated by the toxic substance-like metals. aluminum released due to anthropogenic activities such as mining and industrial uses. aluminium has several industrial uses. the present study was designed to investigate the effect of aluminium ch...

Salicylic acid (SA) may accelerate the cell death of cadmium-stressed roots to avoid cadmium (Cd) uptake by plants or may play positive roles in protecting the stressed roots from Cd-induced damage. To test these hypotheses, we performed a series of split-root hydroponic experiments with one-half of rice (Oryza sativa L. cv. Jiahua 1) roots exposed to 50 microM Cd and the other half not exposed...

Neurodegenerative diseases like Parkinson’s disease (PD),Amyotrophic Lateral Sclerosis (ALS) and Schizophrenia are a group of illness with diverse clinical importance and etiologies. Oxidative stress in which production of highly reactive oxygen species (ROS) and reactive nitrogen species (RNS) overwhelms antioxidant defences, is a feature of many neurological diseases. Lycopene, the most poten...

INTRODUCTION Increased levels of C-Reactive Protein are found in 30-60% on hemodialysis patients and it is closely associated with the progression of atherosclerosis, cardiovascular morbidity and mortality. Non enzymatic antioxidants are antioxidants which primarily retain potentially dangerous ions of iron and copper in their inactive form and thereby prevent its participation in the productio...

OBJECTIVE This study aimed to assess the catalase activity after ischemia and reperfusion and to study the changes of this antioxidant in organs located far from the initial insult. METHODS Eighteen Wistar rats were randomly divided into three groups. 1-Control, 2-Simulation and 3-Ischemia and Reperfusion. In the latter it was done an ischemia of the ileum for 60 minutes followed by reperfusi...
